Group individual Live Chat messages into one conversation in Sent Items

Live Chat sees every individual message sent as a separate sent item even if it's part of the same live chat conversation with 1 person. When going back through Sent Items, this makes it overly large and messy to look back through, especially when some live chats are particularly long. It seems unnecessary to have all messages saved as separate items. Ideally the whole chat itself would be the sent item.
